IMPROVEMENT IN CAR-COUPLINGS.

Specification forming partof Letters Patent No. 170,568, dated November 30, 1875; application filed August 31, 1875.

To all whom it may concern:

Be it known that 1, Cinemas JOHNSON, of Lansing, county of Allamakee and State of Iowa, have invented an Improved Oar-Coupling.

The following description, taken in connection with the accompanying plate of drawings, hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of the invention, by which the same may be distinguished from others of a similar class, together with such parts thereof as are claimed as new and are desired to be secured by Letters Patent of the United States.

My invention relates to that class of couplings which are made use of to connect together the draw-heads of railway-cars; and the nature thereof consists in certain improvements in the construction of the same, herein after shown and described.

In the accompanying plate of drawings, in which corresponding parts are illustrated by the same letters, Figure 1 is a side elevation of a railway-car with my improvements ap plied thereto. Fig. 2 is a view in perspective of the mechanism.

In the drawings, A designates the drawhead, which is provided with a receptacle, B, for the reception of the link 0. D D are levers, having curvilinear arms, which are pivoted together and to theframe E by the pin F. The said levers have arms H, which are connected, .by means of the curvilinear springs I, with the sliding rod K, in such a manner that,

when the said rod is forced backward, the

curvilinear arms close together, forming a.

clutch, which holds the said link in position. The said rod is held in place by the threearmed lever L, having arms I, l, and l. The

arm I is provided with a pointed end, which spring forward, and the said curvilinear armsv to separate.

Having thus described my invention, I claim and desire to secure by Letters Patent The combination of the rod K, three-armed lever L, springsI, spring m, and levers D D, as described.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of January, 1875.

his CHARLES JOHNSON.
